Anyone knows how I can fix a 'not enough input arguments' error? I have the code below, and it points to my if statement. Thanl you!
function C = first(x,y)
if (x >= 0 && y >= 0)
C = x + y;
elseif ((x >= 0) && (y < 0))
C = x + y.^2;
elseif ((x < 0) && (y >= 0))
C = x.^2 + y;
elseif ((x < 0) && (y < 0))
C = x.^2 + y.^2;
end
end

Your function can be called with at most two inputs, and since it uses both inputs on the line you called out it must be called with at least two inputs. So you need to call it with exactly two inputs.

xin = randn()
xin = -1.6940
yin = randn()
yin = -0.3612
output = first(xin, yin)
output = 3.0003
function C = first(x,y)
if (x >= 0 && y >= 0)
C = x + y;
elseif ((x >= 0) && (y < 0))
C = x + y.^2;
elseif ((x < 0) && (y >= 0))
C = x.^2 + y;
elseif ((x < 0) && (y < 0))
C = x.^2 + y.^2;
end
end
